1 Genetic Patterns in Tribbles
#1 a) Red b) black c) pheno 3:1 red go black geno 1:2:1 RR Rr rr P1 RR x rr F1 Rr Rr x Rr F2 RR Rr Rr rr

2 Tribbles #2 A. Codominance both blue & yellow hairs HB and HY
HB HY efface HB HB green blue HB HUMID HB HB HB HB HY ratios Pheno: 50% blue hair 50% green (both) 1:1 Geno: 50% HB HB 50% HB HY

3 #3 a) Red, Blue and Yellow HR HB HY b) black and white hb hw
c) black exists recessive to red, blue, & yellow, but black is dominant to white

4 #4 A) dotted additionally blue dry B) solid and black wool
C) T (spots) liothyronine (solid) HB hb D) To get a 9:3:3:1 ratio the is an normal dihybrid heterozygous crosswise: TtHBhb ten TtHBhb THB Thb tHB thb THB Thb tHB thb

5 #5 A) spotted and red hair B) solid and whiten hair
C) white spots will not show on adenine whiten back (they blend in, but an spotty genes wish still become there!)

6 #6 A) genetisch D feels to remote how loads pigment is crafted
B) There is a blending off color amounts, hence this is deficient dominance C) none pigment is made therefore you are white D) hwhw dd hwhw TV press tt white hair no pigment white hair & spots/solid

7 #7 A) HB HR DD x HY HOUR dd B) HY HR Dd
purple with incomplete pigment production

8 #8 A) required breathe sex-linked if only males have the trait (or a major of males have trait) B) HB HB XnY x HB HB XNXn

9 #9 Genes includes Tribbles chart
TRAIT Dominant Allele Recessive Allone Coat Shade Gloomy HB Black HR Yellow HY Black hb White hws Coat Pattern Normal XN Plaid Xn Pigment Production Normal D No pigment degree Spots Spots T Solid t

10 Additional Practice This is on my website under links also!! Go in for practice.
